Despite becoming the first vanquished presidential candidate to endorse Trump in February and serving as his transition planning chief since May, Christie has yet to donate to Trump’s 2016 campaign, according to the Federal Election Commission filings that cover donations up to Oct. 1.

In the past, the governor has donated the maximum allowed under law to GOP presidential candidates, including $2,500 to Mitt Romney’s 2012 White House bid and $2,000 to George W. Bush’s 2004 reelection effort.
